Chemical and radiological sample results
MS0070007 , Duncan Hill Water Supply
39 of the 73 analytes this system has been tested for have been detected at least once, across 259 samples on record.
The other 34 were tested for and never found. An analyte is counted here if any result on record measured it, so this covers the whole history and not the samples listed below.
Across all 259 samples on record, detections range from September 8, 1993 to July 25, 2026. These figures cover the whole record.
What counts as a non-detect is defined in the help: Less than Indicator. This system’s violations.
What has been detected, ever
Every analyte measured above its reporting level at any point in this system’s record, most often detected first. This is not limited to the samples listed below.

The most recent samples, result by result
The table below lists 161–170 of 259 samples, newest first — collected August 11, 2008 to May 2, 2011. The summary above covers all 259.
47 results from the 10 samples listed here: 8 detected, 39 not detected. Across the whole record it is 330 of 1,445. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
Units in this table
TTHM is recorded on this page in ug/l and mg/l. 1 mg/l = 1,000 ug/l.

| 0 mg/l This result is recorded as a detection, and the figure the agency wrote — "0.00" — is zero to the precision it was written to. Read the zero as "smaller than the written figure resolves", not as "none present". SDWIS holds a separate numeric concentration that Drinking Water Watch does not publish, so this endpoint does not carry it either; no more precise magnitude is available here. , sample collected Aug 11, 2008, sampling point MRT000 | Total Haloacetic Acids (Haa5) 2456 | Jan 1, 2008 – Dec 31, 2010 |

TTHM 2950 EPA method 524.2
- Result
- 13.5 ug/l The agency recorded which kind of limit this result was below, but stored 0.000000000 as the limit itself, which is not a level. The type is published and the value is null. What the limit was is not on record. Whether the result was a detection is a separate column: read resultType.

Total Haloacetic Acids (Haa5) 2456
- Result
- 0 mg/l This result is recorded as a detection, and the figure the agency wrote — "0.00" — is zero to the precision it was written to. Read the zero as "smaller than the written figure resolves", not as "none present". SDWIS holds a separate numeric concentration that Drinking Water Watch does not publish, so this endpoint does not carry it either; no more precise magnitude is available here.
